|discussion=<p>R. L. McGregor (1967, 1968) recognized <i>Echinacea angustifolia</i> var. strigosa as a complex of diploid and tetraploid populations ranging geographically from southeastern Kansas and central Oklahoma to north-central Texas. He noted that var. strigosa is distinguishable by its shorter stature, stems frequently branched, somewhat flexuous, distally strigose to strigose-hirsute that retain, in part, a green color upon drying. A hybrid origin for var. strigosa was suggested based on the morphologic intermediacy of natural populations compared to synthesized hybrids between typical <i>E. angustifolia</i> and <i>E. atrorubens</i> (McGregor 1968). Populations along the southern boundary of the range of var. strigosa are tetraploid. In their morphometric analyses, S. E. Binns et al. (2002) did not recognize var. strigosa; they found it indistinguishable from typical <i>E. angustifolia</i>.</p>
